  Log Message:
  -----------
  Update the ARMv8 builds to specify DUAL_MAPPED_CODE_ZONE.
Fix a security warning in the SecurityPlugin; sqUnixSecurity.c should use getcwd
instead of getwd.
Fix compilation warnings regarding printfs for ARMv8 in sqUnixMain.c.
Change ioAllocateDualMappedCodeZoneOfSize:MethodZone: to
ioAllocateDualMappedCodeZone:OfSize:WritableZone: to get around pointer
scrambling devices on modern linuxes.
